Carpet has undeniable effect in interior decoration, but although carpet has good decoration effect, there are many problems, such as bad cleaning, such as releasing harmful gases, etc. There are many kinds of carpets, whether PVC carpets are poisonous or not, and what are the disadvantages of PVC carpets? Let's have a look.
Whether PVC carpet is toxic
Due to the lack of characteristics of PVC materials, people need to add a lot of additives to stabilize PVC plastics. In fact, pure PVC plastics are not toxic. But after people add a lot of additives to modify, PVC plastics react with toxic substances under the comprehensive effect of a variety of additives, that is to say, these additives can make PVC plastics become a kind of toxic substance The more soft chemical additive phthalein, after using a large number of PVC plastics, has a great impact on the internal kidney, liver and so on.
PVC material itself has no toxicity. If it is not polymerized monomer or degradation product, it will have certain toxicity. Under high temperature and ultraviolet radiation, PVC will degrade. At this time, if people reuse the finished products of degraded PVC plastic, it will easily damage the internal system of human body, resulting in hepatic angiosarcoma.
PVC carpet is loved by customers because of its soft material, stable chemical performance and non-corrosion. It is these advantages that make PVC carpet become the favorite of carpet market and the representative of new carpet materials.
What are the disadvantages of PVC carpet
After long-term use, PVC carpet will inevitably appear aging problems, and compared with other carpets, this aging is more serious. Once aged, it will have an important impact on the aesthetics. If it is a long-term use area, it is not recommended to buy PVC carpet.
Daily maintenance of PVC carpet
1. Usually, we just need to use a vacuum cleaner or a special mop to clean it.
2. If the carpet is accidentally stained with spots or stains, you can directly spray soap water or detergent on the stains, and then use nylon brush to clean them, and then use a rag to clean them, and then use water to clean them.
3. In a year, you can use the wheel of carpet cleaning machine to clean three or four times, and then use detergent and water to do a deep cleaning. Of course, three or four times is not a fixed concept, we can completely determine according to the cleanliness of the carpet. After the overall cleaning, you can also add some bleach to the water to kill the virus.
4. Finally, we need to pay special attention to the point that do not use a strong chemical acid strong alkali solvent cleaning.
What is PVC carpet
PVC carpet is a kind of carpet made of PVC resin material. It is made of PVC and its copolymerized resin as the main raw material, adding fillers, plasticizers, stabilizers, colorants and other auxiliary materials. It is made of continuous sheet-like substrate by uniform mixing, coating process or calendering and extrusion process. It can replace pure wool carpet and chemical fiber carpet.
What is asphalt carpet
Asphalt square carpet, that is to say, with asphalt as backing. Petroleum asphalt is a product of crude oil processing. The source of asphalt is extensive, and then asphalt can be recycled. One disadvantage of asphalt carpet is that it can't be removed and replaced after being laid on the ground for a long time. However, because its price is cheaper than PVC square floor, a few companies are willing to use it.
Pu square carpet
It is to apply a layer of high elastic polyurethane material on the back of the carpet, and cut it into 50-times; 50cm or 100-times; 100cm square carpet. It has good elasticity, comfortable foot feel, sound insulation and heat insulation effect, and belongs to the very environmental protection carpet. In addition, it can also be recycled, but due to the high production cost, the price is not low and the scope of use is narrow.
The difference between PVC and asphalt carpet
material
Asphalt bottom is a layer of asphalt plus a layer of non-woven fabric, different from plastic. PVC bottom is the feeling of ordinary plastic. You can feel it against plastic items.
2. Flexibility
The flexibility of PVC carpet bottom is better than that of asphalt bottom. If you fold it, you will feel elastic. If you fold the asphalt bottom, you will feel cracked.
3. Ground requirements
Asphalt bottom has high requirements on the ground, which requires the ground to be very flat, otherwise it is easy to tilt feet and crack. PVC is relatively more inclusive.
4. Aesthetics
PVC carpet is relatively flat, straight edge, seamless, not easy to take off line and hair, beautiful.
5. Difficult to remove
It is very difficult to remove the asphalt adhesive, especially the ceramic tile and the water ground.
6、 The size stability of PVC bottom is better
In the experiment of measuring dimensional stability, the size of PVC floor felt is only 0.5% smaller than that of the original one when it is heated in microwave oven at 60 ℃ for 24 hours and immersed in water at 60 ℃ for 24 hours.
7. PVC bottom has better weight bearing property
The structure of PVC bottom is more precise, which gives a better supporting force to some heavy furniture, so that the carpet will not be damaged due to its heavy load point, while the asphalt floor is relatively fragile. When a heavy object is placed on it, it will leave an irrecoverable mark on the carpet, making the carpet surface not smooth.
8. The bottom of PVC will produce toxic gas at high temperature
In fact, it is impossible for human beings to survive in this high temperature. People usually die of inhaling smoke and high temperature before the formation of the toxic gas. On the contrary, the asphalt bottom has begun to produce a lot of black smoke at 140 ℃, which has affected the rescue work of firefighters. Remember that at this temperature, human beings still exist.
